Stop using development mode

Rails development mode is easy, useful and fast: we can spin up an app, edit its source, hit reload in a browser and see the result of our changes. But what effect does this workflow have on our code, and does it really help us? In this talk I'll look at the dark side of development mode — where it falls down, what it does wrong, and how it ultimately encourages us to develop software in the wrong way — and suggest an alternative way of working which avoids these disadvantages.
